Miner should tell you in green "Yes". If not, you actually did NOT mine.
May I recommend you to mine Signatum or Denarius? -a skunkash and -a tribus (which has been dramatically optimized in ccminer) respectively
You sure may, but do you think it will be of any good/profitability with such low hashrate? and i have 2 other computers availlable, is it possible to bundle these 3 miners toghetter so they collaborately mine the block toghetter, increasing the total hashrate?
